Scenes A to D represent tiny portions of 0.10 M aqueous solutions of a weak acid HA (red and blue; K-4.4 x 10-5), its conjugate base A (red), or a mixture of the two (only these species are shown): (a) Which scene(s) show(s) a buffer? Scene A Scene B Scene C Scene D (b) What is the pH of each solution? Scene A: 4.36 Scene B: Scene C: Scene D: 4.52 (c) Arrange the scenes (by letter) in sequence, assuming that they represent stages in a weak acid-strong base titration.
